Help me finish the scheme in MATLAB

2 views (last 30 days)
I have created a part of the schema, but I do not know how to complete it. When adding new elements, new errors also appear)
I inserted a screenshot of what I was supposed to get. Please tell me what to add. Thank you in advance.

here are the errors
The model may not give enough information to make it possible to solve for values of some of its variables. Specific advice is given below.
all components and nodal across variables involved
Tie variable 'Voltage_Sensor.p.v' (Voltage) to a definite value, for example by connecting an appropriate domain reference block.
Dependency found among topology equations. Check for missing reference node.

This issue is that because an ideal transformer is used, it is perfectly isolated from the rest of the circuit. Unfortunately, Simscape doesn't support pure floating circuits. This can be solved 2 ways. You can place an electrical reference under R_H (it is resistor 3 in your simulink model) or you can place a very large resistance between both sides of the transformer. I recommend adding the electrical reference as it won't change your results.
